SAW-GUIDE.

SPECIFICATION forming part of Letters Patent No. 789,005, dated May 2, 1905.

Application filed July 26,1904. Serial No. 218,257.

To all whom it may concern.-

Be it known that we, ALFRED IICONKEY and CHARLES C. BRADLEY, citizens of the United States, residing at Chloride, in the county of Mohave and Territory of Arizona, have invented a new and useful Saw-Guide, of which the following is a specification.

This invention relates to guides for crosscut-saws, the object of the invention being to enable a saw of this class to be guided accurately, so as to make a smooth straight out at the desired point.

With this and other ends in view, which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts, which will be herein after full y described, and particularly pointed out in the claim.

In the accompanying drawings has been illustrated a simple and preferred form of embodiment of the invention,-it being, however, understood that no limitation is necessarily made to the precise structural details therein '2 5 exhibited, but that the right is reserved to any changes, alterations, and modifications to which recourse may be had without departing from the spirit or sacrificing the advantages of the invention.

0 In said drawings, Figure 1 is a perspective view illustrating theimproved saw-guiding device in position for operation. Fig. 2 is an end view of one of the end members' Fig. 8 is a side view showing the upper ends of the 3 5 end members and the cross-bar connecting the same.

Corresponding parts in the several figures are indicated by similar numerals of reference.

This improved saw-guiding device includes two end members E E, each of which includes a pair of uprights 1 1, connected at their up per ends, as at '2, and provided at their lower ends with outturned supporting members 3 3, having downwardly-extending spurs A. Each of these end members, as will be readily understood, may be easily bent from a single strip of material, such as iron or steel. In bending these devices the side pieces or uprights should be spaced apart slightly in ex- 5 cess of the thickness of the blade of an ordinary crosscut-saw, except at their upper ends, where enlarged eyes 5 are provided, and at their extreme lower ends, where the uprights l 1 are made slightly divergent, as shown at 6, in order to enable the saw-guiding devices to be readily placed in operative position with relation to the saw-blade.

The improved saw-guiding device comprises two of the end members E E, which are constructed exactly alike. Each of said end members is provided near its upper end with a transverse threaded perforation 7, in which is fitted a set-screw 8.

9 designates a connecting-bar which is pro- 5 vided at intervals with perforations 10. The ends of this connecting-bar are inserted into the eyes 5 at the upper ends of the end members, where by tightening the set-screws 8 so as to permit the latter to extend through 7 openings 10 the said cross-bar is made secure, thus serving to connect the end members together at any desired distance apart, which is graded according to the location of the perforations 1O engaged by the set-screws 8. Thus when wide timbers are to be operated upon the end members E will be spaced apart a distance almost equal to the width of the timbers. When narrow timbers are to be sawed OK, the distance between the end members E E will be correspondingly reduced.

This invention is designed especially for trimming or squaring timbers intended to be used in bridges, buildings, and the like. When timbers of this kind, which are usually 8 5 of great dimensions, are to be trimmed with a crosscut-saw, considerable difficulty is oftentimes experienced with starting the cut aright. Especially is this trouble experienced in case of high winds, when the wind will take 9 hold of the saw-blade, making it almost impossible to properly guide the latter. Now by this invention when the timber has been marked at the place where it is to be cut the edge is placed upon the mark and the saw is held steady while the guiding device is clipped over the back of the saw until it rests upon the timber. By a few light blows the spurs or prongs 4 will be driven into the timber, thus steadying and supporting the guiding device while the saw is being operated to make the cut.

This device is applicable not only to large crosscut-saws, which are frequently from six to eight feet long, but it may with equally satisfactory results be used in connection with crosscut-saws which are of a size to be operated by one man.

Having thus described the invention, what is claimed is A saw-guide including a pair of guiding members each composed of a strap bent to form spaced legs provided with outturned supporting members at their lower ends, and

an enlarged widened portion forming an eye at the bent portion of said strap between the upper ends of the legs, in combination with a connecting-bar extending through the eyes at the upper ends of the guiding members, and means for adj ustably connecting said guide members and connecting-bar.

In testimony that we claim the foregoing as our own we have hereto aflixed our signatures in the presence of two witnesses.
